Proof-of-Humanity smart contract
You must use the isRegistered(address _party) function to determine if an address is or isn't registered.
Do not use getSubmissionInfo(address _submissionId).registered since this only returns the state of the submissionInfo variable without considering submission expiration date.
If you are referring to Proof Of Humanity, we advise you to either:
- Reference the main contract and have a mechanism to switch to a new one.
- Reference the proxy which will automatically be updated in case of new versions (like one allowing anonymous accounts). The proxy also acts as a pseudo-ERC20 returning a balance of 1 VOTE to people registered in the registry. This allows to use it for some voting systems using tokens such as Snapshot.
